SPECIFICATION forming part of Letters Patent No. 656,420, dated. August 2i, Ieoo.

i Applioationlled January 2, 1900. nSerial No. 49. (No model.)

.T ctZZ whom it may concern/3 I- I Be it known Athat I, FRANK `PYEfa subject of the Queen of Great Britain, anda resident of the city and county of Philadelphia, State of Pennsylvania, `have invented certain new and useful Improvements in Water-Puriiiers for Steam-Boilers, of which the following is a specification.. p I I y I My invention relates `to improvements in overhead boilerlfeeding devices, and more` particularly to improvements in the device for whichLetters Patent of the United States were issued to me on October 3, 1899, No. 634,272, the object of mypresent invention being to improve the details of my apparatus, as hereinafter fully described. I

In the accompanying drawings, forming partof this specification, `and in which simi- `plan of Fig. 2 5' Fig. 4, a section of Fig. 2 on `lar letters of reference indicate similarparts line C D; fFig. 5,al section of Fig. l online A B; Fig. 6, a perspectiveview of part` of rod carrying cleaning projections adaptedto enter water-passages in feeding and blow-od tube; Fig. 7, a perspective view,partly.broken away, ofthe upper drum of a boiler and of a modification of `my sedimentfcollecting box` and water-feeding andIblow-off tube; Fig. 8, a central sectionalelevation` through the gland through .which'theouter endoi clean, ing-rod` passes. e `L 3 I r I o is a steamlboiler, inthedrawings shown as the upper drum of a water-tube boiler;. o,

` a metal box open atthe top andfurnished along the sides of the opening withl downwardly-projecting flanges d, which are furnished at intervals withopenings Z7. The boxe is placed in `the boiler, the water-line in the latter. reachingslightly above the bottom of the flanges d. II I I e is a feed-waterpipepassing into theboiler and thence into box c. In `Figgl the pipe e passes completely through the boilerpand box `union p, Figs. 1 and 2. a y a rrepresents legs carried by box c,whichhold boxe, the stop-cocks fg both being at the front end ot' the boiler.

,a h'shows openings in the top of pipe e. The

ends of these openings are beveled from the v.top downward, `as shown in the drawings.

Oneor twoof the rear openings are placed on Atop of the pipethat is, along its central line. The other openings areplaced one to `one side of` the central line, the next to the `other side of this line, and so on, and each opening is preferably somewhatlarger than theone directly infront of it, as shown best inFig.2. I y II s e t' is aprod passing through pipe e andfurnished with upwardly-projecting ingers j, whichpass through the openings h in pipe e,

`and-which are furnished vwith cotter-pins 7c, `which engage top ofv pipe e and hold the rod `in place. An extension ot' rod/1l passes out of pipe e through a gland Z and is furnished with an operating-handle m. The rod t', with its fingers j, can be moved backandforth in ordei` to clear the openings h of sediment, I which without some such arrangement would quicklyclose up Vthe latter. `The holes hin theforward end of the pipe e are staggered, f

as shown, so that `,therewillbe no tendency e of the rod to turn upon its axis, andthe rear holes are larger than the forward onesin order to equalize the flow of water atlthe forward and rear portions ofthe pipe. VThe pipe e passes through glands n,carried by the `forward andrear ends of theboxc in order to permit expansion `without dangerous results.

For the same reason thepipee ismade in `two or more pieces of different diameters, which areunited by glands o, the smaller piece Ibeing adapted to `slide 'backwardor forward within the larger. For purposes ofconstruce tion the rear ends of pipe e" are secured by a this box clear ofthe bottom of boiler ct.`

s represents removable `stays passing from oneside to the `other of the opening in the top of box c, which prevent the sidesof this openA ing from spreading.`

t represents straps theupper ends'of which are secured to the sides of the openings in box c andthe lower ends of which support the pipe e.

u, Figs. l and 7, is an opening in the for- 'Ward end of box c, deeper than the longitudinal opening in the top of the box and connected therewith, through which the water passing to this box from pipe e escapes to the boiler. s

In operationwater is admitted to the pipe e from any suitable source of supply and escapes through openings h to the interior of box c, within which the Water lies comparatively still and in which all or a greater part of the sediment carried by the water is deposited. Frombox c the water escapes through opening u to the boiler. Any tendency of the water to surge across the top of the box is checked by the flanges d.. vThe box is preferably'made oval in cross-section to correspond with the usual shape and size of the -manhole in the boiler end, and it isvv placed in the boilerr by being passed through this hole. f

fIn Fig. l the pipe e is shown passing clear through the boiler. To admit-feed-water in this construction, the stop-cocky is opened,` While the stop-cock g is closed.` In order to blow out the boiler, the cock f is closed and the cock g opened.

In Fig. 7 boththe feed and blow-olf cocks are at the forward end of the boiler and the rear end of pipe e is plugged, both the feed and discharge taking place through the forward end of this pipe, as will be readily uny derstood from the drawings.

passes. the rod' is not in use is adapted to rest against a seat w on the interior of the gland.V sc is a disk carried.` by rod i inside of disk r and of greater diameter than this disk, but which does not come to a seat, the rpurpose of which is when the boiler is being blown out to direct a current of water against the seat w in order to keep it clean'.v y is a short ysection of pipe which may be screwed on gland Z in orderto cover and protect the operating-handlem and to `protect/the vpacking from the heat of the l. In a'boiler feeder and purifier, incombination, a boiler.,v a sediment-collecting box within said boiler open at the top, a feed-wapipe and operated from without said boiler whereby said openings may be freed from obstructions at will. v

2. In combination a boiler, aSediment-collecting box, Within said boiler, open at its top, a feed-Water pipe within said box furnished with openings on its top, a rod within said box, extending out of said boiler and iingers carried by said rod entering the holes in said feed-pipe. Y

, 3.' In combination, aboiler, asediment-collecting box Within said boiler and open at its top, a feed-Water pipe within said box furnished with openings on its top, some of which are staggered, a gland on said pipe without the boiler, a rodV passing through said gland, fingers carried by said rod and passing through said openings in said pipe', and pins passing through said fingers and resting on top of said pipe.

4. vIn a water-purifier for steam-boilers the combination with the finger-carrying rod, the

perforated feed-pipe, and the gland on said pipe through which said rod passes, of aseat on said gland, a disk carried by said rod ladapted to rest on said seat, and a ydisk on said rod separate from and inside said first disk, all substantially as and for the purposes vset forth.

5. In combination, a boiler, asedinient-collecting box within said boiler open atits top,

ynotched iianges secured -along the sides of said opening, movable stays passing across and securedfto the sides of said opening, and a feed-pipe Within said box furnishedwith a telescopic joint to permit `expansion and contraction. l i 6. In combination, a boiler, asediment-collecting box, oval in cross-section, Within said boiler and furnished with a longitudinal opening along its top and with an opening connected with, but lower than said longitudinal opening, legs supporting said box, a feed-*pipe within said box furnished with openings along its top, a rod passing from the outside of said boiler into said feed-pipe, fingers on said rod passing through the openings in said pipe, glands carried by the ends of said box through which said pipe `passes and telescopic joints on said pipe to permit expansion and contraction. .Y
